firmware upgrade encryption using mupgrade
Posted: Mon Nov 18, 2019 7:06 pm
In ESP-IDF, the the default process for updating firmware rely on TLS to encrypt and hide the firmware update from users (or attackers).
When using the mupgrade component, there does not seem to be any encryption other than the WPA password set for the mesh network. A user could then capture the update binary if knowing the AP password.
Am I correct or did I miss something?
